When it is necessary to adjust the space between the supporting plate 13 and the buffer member 50, the first locking member 33 and the second locking member 35 are detached from the adjusting rod 31, and the inserting degree of the adjusting rod 31 in the adjusting hole 131 is adjusted to ensure that the space between the supporting plate 13 and the buffer member 50 reaches a proper range, and then the first locking member 33 and the second locking member 35 are clamped in the corresponding locking position.

It can be understood that the first locking member 33 and the second locking member 35 can also have a clamping structure. The first locking member 33 and the second locking member 35 can be clamped at any positions of the adjusting rod 31, and the purpose of adjusting the space between the supporting plate 13 and the buffer member 50 can also be achieved. In some embodiments, the outer surface of the adjusting rod 31 defines the connecting parts 311 arranged continuously.

Referring to FIG. 6, the buffer member 50 includes a connecting plate 53 and a buffer plate 51, the connecting plate 53 is connected to the end face of the adjusting rod 31, and the buffer plate 51 is connected to the surface of the connecting plate 53 away from the adjusting rod 31.

In some embodiments, the connecting plate 53 and the adjusting rod 31 may be of an integral structure for installation operation. The plate-shaped buffer plate 51 and the connecting plate 53 can increase the contact area between the display panel and the buffer plate 51, thereby dispersing the force of the display surface hitting the buffer plate 51, and thus better protecting the display panel from damage. The adjusting rod 31 has a columnar shape, and the cross section of the adjusting rod 31 may be circular or polygonal.

In some embodiments of the present disclosure, the buffer structure 100 includes a plurality of adjusting rods 31, and the supporting plate 13 includes a plurality of adjusting holes 131. One end of each adjusting rod 31 all connects to the buffer member 50, and the other end of each adjusting rod 31 passes through one corresponding adjusting hole 131.

In some embodiments, the plurality of adjustment rods 31 are spaced from each other, and the extension lengths of the plurality of adjustment rods 31 are the same and can be adjusted synchronously. The plurality of adjusting rods 31 can make the support of the adjusting component 30 to the buffer plate 51 more uniform and stable, and the force of the display panel to the buffer structure 100 is more uniform, so that the reaction force of the buffer structure 100 to the display panel is more uniform and stable.

Referring to FIG. 4, the plurality of adjusting rods 31 are arranged side by side, the connecting plate 53 has a long side with a long dimension and a short side with a short dimension, and the plurality of adjusting rods 31 are arranged side by side along the extending direction of the long side. In some embodiments, the connecting plate 53 has two opposite long sides and two opposite short sides, and the arrangement directions of the plurality of adjusting rods 31 coincide with the extension directions of the long sides, so that the connecting plate 53 is more stably supported along the direction of its larger size. It may be understood that the connecting plate 53 may have other shapes such as trapezoid, triangle or circle, etc., and the arrangement directions of the plurality of adjusting rods 31 are the same as the directions of the portion of the connecting plate 53 having a larger size. If the connecting plate 53 has the same size in all directions, for example, the connecting plate 53 is circular, the arrangement direction of the adjusting rods 31 is any direction passing through the center of the circle.

Furthermore, the supporting plate 13 defines a limit groove 133, the adjustment hole 131 is formed in the bottom wall of the limit groove 133, and the buffer member 50 matches with the limit groove 133 in size.

In some embodiments, when the space between the connecting plate 53 and the supporting plate 13 is close enough, the movement of the buffer member 50 is limited by the limit groove 133, so that the buffer member 50 can move more smoothly when it is acted on by the display panel, and thus the buffer force applied to the display panel is more gentle.

In some embodiments of the present disclosure, the fixing structure has two supporting plates 13 cooperatively form an angle, and the buffer structure 100 includes two adjusting component 30 and two buffer members 50. One supporting plate 13, one adjusting component 30, and one buffer member 50 are cooperatively mounted together, and the two buffer members 50 both face the display panel in the box body 200.

Furthermore, the fixing frame 10 includes two mounting plates 11, each of the two mounting plates 11 is located on an extension line of one supporting plate 13. An angle is defined between the two mounting plates 11. After the mounting plates 11 are connected to the box body 200, the two mounting plates 11 cooperatively forming an angle limit the fall-off of the buffer structure 100 from two directions, so that the connection between the buffer structure 100 and the box body 200 is more stable.

Electively, the two supporting plates 13 are perpendicular to each other, and the two mounting plates 11 are also perpendicular to each other, and the fixing structure is generally cross shaped.

Furthermore, the edge of the mounting plate 11 away from the supporting plate 13 bends and extends sideways.

The second side plates 113 of the two mounting plates 11 extend in opposite directions respectively.

In some embodiments of the present disclosure, the buffer structure 100 should be mainly set at the corner position in the box body 200 of the packaging box, so as to prevent the four corners of the display panel from colliding with the buffer structure 100 at a short distance from the front, thus playing a better role in protecting the display panel, and adjusting the adjusting component 30, thus ensuring that the space between the display panel and the buffer structure 100 is maintained within a safe range.

When the buffer member 50 receives the force of the display panel, the force is transmitted to the supporting plate 13 through the adjusting component 30 and then transmitted to the box body 200, thereby protecting the buffer structure 100 and preventing the buffer structure 100 from being damaged.

Furthermore, the inserting groove 202 includes a first inserting section 2021 and a second inserting section 2022 that communicate with each other.
